摘要：
The removal of low concentrations of toluene using non-thermal plasma (NTP) coupled with MnCe/La/cordierite honeycomb (CHB) catalysts had been investigated in this study. Mn/CHB, Mn-Ce/CHB, Mn-La/CHB catalysts were prepared for the experiment. The removal rate and removal amount of toluene, generation of O-3 and main aerosol by-products for different reactors had been investigated. The catalysts were characterized by BET, SEM, XRD and H-2-TPR. The results showed that rare earth catalysts could improve the removal efficiency of toluene and the degree of mineralization effectively. Mn-La/CHB catalyst had the better catalytic performance than Mn-Ce/CHB catalyst. The toluene removal rate and removal amount of Mn-La/CHB catalyst could be achieved at 76.31% and 159.0 mg/h, respectively, while the initial concentration of toluene being 600 mg/m(3), discharge voltage being 22kV and gas flow rate being 6 L/min. Moreover, H-2-TPR results showed that the low-temperature activity and capability of O-3 adsorption enhanced with the loading of rare earth catalysts. Catalysts were contributed to the decomposition of O-3.
